IMPROVEMENT IN MACHINES FOR FINISHING PRINTED SHEETS OF PAPER.

Specification forming part of Letters Patent No. 196,692, dated October30, 1877; application filed August 2, 1877.

To all whom it may concern:

Be it known that I,JAMEs MORRIS, of Liverpool, in the coimty ofLancaster, England, have invented a new and useful Improvement inMachines for Finishing Printed Sheets of Paper, which improvement isfully set forth in the following specification, reference being had tothe accompanying drawings.

The object of my invention is to simplify and render more efficientmachines for finishing printed sheets of paper, similar to the machinefor which I obtained United States Letters Patent N 0. 146,605, datedJanuary 20, 1874.

Figure 1 is a side elevation, partly in section, Fig. 2 a sideelevation, and Fig. 3 a front view, of my improved machine for finishingprinted sheets of paper.

Like letters denote the same parts in all the views, and the arrows showthe direction of motion of the parts.

1, frame-work; 5, smooth heated set-off rolls, between which the paperto be finished passes; 3, perforated or open-work container, caused tovibrate by the levers 4, so as to deposit whiting or other powderymatter in a shower directly on the smooth set-off rolls 5.

The object of depositing the whiting or powdery matter in a showerdirectly on the set-off rolls is to insure that the ink set-off shall beevenly coated with the said whiting or powdery matter. 6 are rotatingbrushes to wipe or clean the ink set-off and whiting or powdery matterfrom off the surface of the rolls 5.

The bristles on the brushes 6 may be placed spirally or otherwise, andthe said brushes may be caused to rotate in either direction or at anyrate of speed, and they may be made to have a longitudinal reciprocatingmotion. Wires or the like may be used instead of bristles on thebrushes,

In some cases two brushes may be sufficient to clean each set-off roll;but I prefer to employ three brushes for each, two rotating in the samedirection as the set-off roll, and one in the opposite direction.

7 are straight edges or pieces, against which 7 the bristles of thebrushes strike, so as to knock the ink and whiting or powdery matterfrom off such brushes into the troughs, receptacles, or containers 8,whence the refuse matter may be removed, as desired. 9 are fingers orneedles, so arranged as to be adjustable longitudinally and radiallyalong the bars 10, and secured in position by means of the set-screws11.

The object of the said fingers or needles is to insure that the papershall not be carried round with the rolls, but shall be delivered ontothe receiving traveling tapes, cords, or apron 16.

16 X is a carrying-board. 17 represent travel ing tapes, cords, or apronfor conveying the printed sheets or webs to the rolls; 12, casing; 13,exhaust pipe through which any floating dust is drawn ofi; 15, pipesthrough which steam passes to heat the rolls 5.

I claim 1. The vibrating perforated or open-work containers, arranged todeposit whiting or powdery matter directly onto the set-off rolls, andin combination with said roll, for the purpose set forth.

2. The rotating brushes, in combination with the set-off rolls, andarranged to act directly thereon, for removing the whiting or likematerial and ink from the surface of the rolls, substantially asspecified.

3. The straight edges or pieces 7, against which the bristles, or theirequivalents, of the brushes 6 strike, for the purpose set forth.

4. The troughs, receptacles, or containers 8, for collecting the refusematter thrown off from the brushes 6, substantially as set forth.

5. The adjustable fingers 9, arranged substantially as and forv thepurposes set forth.

6. The tapes, cords, or apron 16, and also 17, made to travel, for thepurposes set forth.

7. In a machine for finishing printed sheets, the combination of thebrushes 6 and straight edges or pieces 7, arranged and operatingsubstantially as and for the purposes set forth.

8. In a machine for finishing printed sheets, the combination of thebrushes 6, straight edges or pieces 7, and troughs 8, arranged andoperating substantially as and for the purposes set forth.

9. In a machine for finishing printed sheets, the combination of theheated rolls 5 and adthe combination of the heated rolls 5, brushes 6,straight edges or pieces 7, and troughs 8, arranged and operatingsubstantially as and for the purposes set forth.

12. In a machine for finishing printed sheets, the combination of theheated rolls 5, brushes 6, straight edges or pieces 7, troughs 8, andadjustable fingers 9, arranged and operating substantially as and forthe purposes set forth.

JAMES MORRIS.
